Print Master-Multi detail records

Hello,
I'm trying to create a customized print page, that contains data from 3 tables:

• orders
  
• order items
  
• used raw materials
  Orders is the master table and the other two are detail tables belonging to the order.
  
  What I'd like to get as a result is a printing page that contains the selected fields for the order, and the records from the two detail tables.
  Maybe this question has already been answered, but I didn't find a similar solution.
  
  I already have an order edit page that displays the master fields and the two detail table records, but I can't get it printed.
  Could someone please help me what's the basic concept for this? I don't need a detailed guide how to do it, just the guidelines.
  Thank you
